Questions & Answers Ask a Product Question
Q:

What is the bend radius of the u-bend (180 deg) pipes? Or, at least, what's the distance between? Has anyone used these 180 bends for the over the axle hoop on their custom builds?

Asked by JOHN A on April 13, 2018

A:

Thank you for your question. The Summit 670146 Universal Rod Builder Exhaust Kits include U-bends which have a 3.75 in. centerline bend radius and a distance of 5 in. in between the two legs.

Q:

Has anyone used this setup when designing their turbo charge piping etc? Cold side is 2.5" which this kit would be perfect. Thanks

Asked by DEREK S on June 30, 2018

A:

Yes, it will work well to plumb your turbo just plan carefully and keep welding to a minimum.

Answer This Question

Q:

what gauge tube is this?
I see there is a version that is cheaper and 16ga, I can assume this is thicker?

Asked by EDWARD on October 23, 2016

A:

16ga is the correct size it is also aluminized steel not mild steel. used this kit to replace part of the exhaust on my 1979 corvette after replacing transmission with a 700r, worked great for me !

This is an excellent quality kit. It had everything I needed to go front to back on my car. It was a lot of work to get the angles right and do the welds so there were no ugly joints but the end result was worth the effort!

I used this kit on my 1974 Chevy k10 short bed, LS swap,th350, 208c transfer case. Good product, I do wish that they would get rid of the 180_° bends, not sure where you use those? But all parts fit together nicely and had lots of parts extra. Welded my exhaust. Loving it so far, you will have to modify some parts. If you want a kit that just fits and doesn't make you think, buy something specific for your vehicle ...read more
